  • Patent number: 5444750
    Abstract: Apparatus for counting and selectively voiding tickets. An input bin is provided wherein a stack of tickets are initially queued. Using a conveyor, each ticket is advanced from the input bin past a sensing device. The sensing device detects the presence of each ticket and produces a signal indicative of the passage of each ticket past the sensing device. This signal is conveyed to an electronic counting device that maintains a cumulative total count of the tickets. The apparatus may be set to continuously count any tickets placed in the input bin or set to stop after counting a predetermined number of tickets. The apparatus also includes a punch that is selectively controlled to enable the optional voiding of each ticket as it is counted.

  • Patent number: 4799413
    Abstract: A cutting arrangement for the cutting to shape of a web-shaped material, such as paper webs (2) in printing presses. The arrangement consists of a cutting element (8) and a backing element (3) over which the paper web runs, in conjunction with which one edge of the cutting element (8) is brought intermittently into contact with the paper web for the purpose of cutting through the paper web in its longitudinal sense. The cutting element (8) is so arranged as to change its position intermittently in relation to the paper web (2) between a first, advanced position in which the cutting element (8) uses its edge to cut through the paper web as it passes over the backing element and a second, withdrawn position in relation to the paper web in which the cutting element is not in contact with the paper web. The intermittent movements of the arm between the first and the second position are controlled by a control unit (12) depending on the advance of the paper web (2).

  • Patent number: 4646598
    Abstract: The present invention relates to a brick cutting and handling apparatus having a movable wire bank cutter assembly. The wire bank cutter assembly is movably confined within a holding frame structure and is movable generally vertically up and down therein in a rectilinear fashion. As a respective brick slug is pushed through the wire bank cutter assembly, the wire bank cutter assembly is moved generally downwardly. This vertical downward movement tends to form a swirl-like configuration on opposite sides of the individual cut brick. Further, roots, sprigs and other such debris are often caught on the respective wires of the wire bank cutter assembly as respective brick slugs are pushed therethrough. This vertical up and down movement of the wire bank cutter assembly tends to pull such roots, sprigs, etc., from the respective slugs and once pulled from the slug or slugs, these same roots, sprigs, etc., are stripped therefrom.
